There should be a bent washer over the nut to stop it from turning. Have a good look.
Flatten the bent washer with a flat cold chisel, gently, as you need it again! Put the bike in top gear to hold the sprocket and use a spanner 27mm to undo the nut. It is a clockwise thread.
When you put a sprocket back on, don't forget the bent washer and a drop of Loctite Threadlock will help to hold it on.

How do i remove the front sprocket on my 91 softail custom?

I assume you're talking about the front belt drive sprocket. First, disconnect the negative side of the battery. If you haven't already done so, you must drain the primary and remove the outer primary cover. Then you must take the engine compensator nut off and the nut that holds the primary chain adjuster. Remove the circlip and pull the clutch adjuster plate out of the center of the clutch. The mainshaft nut in the hole in the center of the clutch. The nut has LEFT-HANDED THREADS on it. Remove the engine compensator sprocket, primary chain, and clutch assembly all together. Then remove the small bolt that holds the jackshaft in and remove it and the coupling. Remove the starter. Then, take the bolts out and remove the inner primary cover. Now, you can see the front belt drive sprocket. You must take the large nut off the sprocket. It too has LEFT-HANDED THREADS. You need a special deep socket and a sprocket locking tool to get the sprocket off and retorque the nut when you put it back on. This is a major job requiring a fair amount of disassembly of the bike. If you're going to change the belt, the rear wheel and swingarm must come out as well. I would high recommend that you purchase a service manual to help with this project.

Good Luck

1992 fxrs. just split my Final drive belt, can I fix it at home? ok/good mech. knowledge but will I have problems with clutch etc. Any "traps" or handy tips would be good.

yes, you can replace the belt yourself but it's quite a job. You must pull the primary, the engine sprocket and clutch assembly, the starter, the inner primary, the rear wheel, and the swing arm. You'll need an air wrench to remove the engine sprocket nut and the clutch nut unless you have a "locking bar" or something to wedge into the primary chain to lock the primary up so you can retorque the engine and clutch nuts properly. The engine nut torques to 150-165 foot pounds of torque. The clutch nut has LEFT HANDED THREADS and torques to 60-80 foot pounds. Put one line of Loctite Red #271 in each nut. As long as you don't have to pull the transmission belt pulley off, this is all you need. Most of the time, you can work the belt onto the pulley. If you can't, you'll need the special socket to loosen and tighten the large nut on the pulley and a "locking device" for it as well. The nut on the front pulley torques to at least 150 foot pounds as well and is LEFT HANDED threads as well.

Good Luck

I need to replace the harmonic balance seal.

THE thread is a std Left hand to undo But you will need a 3/4 drive100 lbs air rattle gun to both undo and redo up the bolt on front pully.. BUT there is another way and that is as you say a big breaker bar and a good socket, but you will have to take off the starter motor and put a good fitting bar into the starter ring teeth and turn it to the top and dont let it slip out of the teeth and once locked into place gently put pressure on and undo the bolt..
But its unusual for the seal to leak on its own as its mostly due to either the front pully has worn a grove in it or the crankshaft bearing is also worn, so check the front pully for wear first. Ron

Iam trying to replace the drive belt on my standard fxr have removed primary cover undone the left handed threaded nut on the clutch but am unable to undo the compensating sprocket nut, the w/shop manual...

The compensating sprocket nut is indeed right hand threads. It is torqued to 150-165 foot pounds of torque and usually has Locktite 271 (red) in it. A lot of mechanics go overboard with the Loctite. I've seen the entire inside of the nut "painted" with this stuff. The book calls for "two lines" of the stuff when putting the nut back on.

The easiest way to get the nut off is with a GOOD air wrench. I bought one of those Ingersol-Rand Titanium air wrenches. I've seen nuts on so tight that I've had to use a 3/4" air wrench to get them off. If you don't want to purchase an air wrench, load the bike on a trailer and take it to a tire store. Ask them to take the nut off for you. Usually they'll do it free but they may charge you a couple of dollars. It is worth a couple of dollars to get the nut off.

When putting the bike back together, the compensator sprocket torques to 150-165 ft lbs. of torque with two lines of 271 Loctite in it. The clutch hub nut torques 60-80 ft. lbs. left handed with one line of 271 Locktite. Make sure your torque wrench will torque in the left handed direction. Not all wrenches will.
Good Luck.
